Ranking of Software Code Parts

3. The method of claim 1 further comprising normalizing each of the constituent metrics before the step of ranking the plurality of parts of the software code.

4. The method of claim 1 wherein determining one or more of the constituent metrics comprises excluding, from the determination, previous alterations associated with a time indication outside a time window of the change history register.

7. The method of claim 1 further comprising, for each of the plurality of parts of the software code, determining a combined metric based on the plurality of constituent metrics, and wherein ranking the plurality of parts of the software code based on their respective constituent metrics comprises ranking the plurality of parts of the software code based on their respective combined metrics.

8. The method of claim 1, wherein the signal indicative of the one or more candidate parts is configured to cause control of hardware utilization associated with alteration software code.

10. A computer program product comprising a non-transitory computer readable medium, having thereon a computer program comprising program instructions, the computer program being loadable into a data processing unit and configured to cause execution of the method according to claim 1 when the computer program is run by the data processing unit.

11. A non-transitory computer-readable medium comprising a computer program loadable into a data processing unit and configured to cause execution of the method according to claim 1 when the computer program is run by the data processing unit.

13. The arrangement of claim 12, wherein the signal indicative of the one or more candidate parts is configured to cause control of hardware utilization associated with alteration software code.

14. An apparatus for hardware utilization control comprising the arrangement for ranking a plurality of parts of a software code according to claim 12, wherein the controlling circuitry is further configured to cause control of hardware utilization associated with alteration of the software code based on the signal indicative of the one or more candidate parts.

15. A control node comprising the arrangement of claim 12.
